The 208 volt configuration is one phase of a three phase source at 240 volts, where the 208 volt circuit is connected between the center tap of one 240 volt phase (usually a grounded neutral, in the style of a standard 120/240 split phase system) and the high delta connection on either of the other two phases.
208 circuit would consist of two phases of a 208 volt wye system or could be all three phases. The voltage between conductors would be 208 volts. The voltage to ground from any phase would be 120 volts. A 240 volt delta system would give you a high leg to ground, somewhere around 190 volts and the other two would be 120 volts to ground.

What AWG cable for 200' x 208 volt three phase 250 amp circuit?
A wire size of 250 MCM will limit the voltage drop to 3% over a distance of 200 feet.
What size overcurrent protection device is required to protect the secondary of a three phase 75kva and 208 v transformer supplying a 150 amp continuous load?
If you're asking about load sizing, I think you already have the answer (at least 150A, although you could go up to 208 for full load, and maybe higher if you can overload the transformer). If you're talking about short circuit rating, you have entirely the wrong information. Short circuit rating will tell you if the fuse (if you're using fusing) mounting is rated to interrupt the available fault current.
What is a circuit with no load?
An open circuit or a short-circuit (if that circuit is complete).
What ways are there to convert 480 3 Phase to 208 3 phase?
It depends on your definition of efficiency. 480 can certainly push more power than 208 through the same size conductors, but it would not be efficient to wire a motor for 480 when 208 was all that was needed.
How is a series circuit and a parallel circuit like their circuit names?
A series circuit is actually in series, but a parallel circuit, is Parallel
Why won't a 230-460 volt motor work on a 120-208 volt circuit?
Because its designed to operate at 230-460, not 120-208.
How do you get 208 on a single wire?
You don't. Every circuit needs a return wire back to the source.
How many wires do you need for a 208 v circuit?
208 v is a three-phase supply voltage used in North America, carried on a 4-wire system. The voltage between one of the three live wires and the neutral wire is 120 v and a single-phase supply can be taken by using one live and the neutral. If in doubt about the connection consult an electrician.
What is the Power dissipated allowed by a circuit breaker with 208 volts and 5 amps?
1,040 watts or 1.04 KW.
How do you covert 120 volts to 208 volts?
Single phase or three phase? 120/208 would be measured hot to ground for 120 and hot to hot (phase to phase) for the 208 reading. Any hot to ground will read 120 and any two phases together will read 208.
Can you power a three phase motor and a 208 motor on the same circuit?
Yes, with the proper control equipment ahead of the motors.
What is 208 over 1000?
208/10 = 20.8 208/100 = 2.08 208/1,000 = 0.208
What is 60 percent off on 208?
60% of on 208 = 40% left of 208 = 208*40/100 = 83.2
How many square feet are in 208 feet x 208 feet?
It is: 208 times 208 = 43,264 square feet
What one eighth of 208?
208 divided by 8 is one eighth of 208
Can you use an existing 30amp circuit for my new cook top which calls for 208v240v?
It depends on the voltage of the 30-amp circuit, which has to be 208 or 240 v, and it also depends on how much current the cook top takes, which must be less than 30 amps. If those two conditions are met you can use the existing circuit.
What is 208 plus 70 percent?
208 plus 70% = 208.770% more than 208 = 1.7 x 208 = 353.6
